From the largest retailer of crib mattresses website: “The Crib Mattress's
top inside layer is Fireblocker, providing gentle sleeping and safety.” We
disagree on safety. We know this system contains 10% Boric Acid and 2.4%
Antimony. European researchers measured and proved Antimony leaches through
vinyl on crib mattresses, and linked this to Sudden Infant Death Syndrome
(SIDS). High levels of Antimony were found in the livers of dissected dead
human infants. Europe has been moving away from using flame retardants and
requires them be proven safe before being used.

Toxin Free Crib Mattresses

Strobel Crib mattresses are Conforming Hypo-Allergenic Pure Urethane or
Latex Foam Cores, not inexpensive innersprings with chemically saturated
cotton batting. Waterproof covers wipe clean
easily and feature seamless tops. There is no stitching on the top surface
edges where moisture and bacteria can enter the mattress. Bottom zippered
cover allows you to be sure even the inside of the mattress is clean.
27.5x52x5.5" Young children are the most vulnerable to toxic exposures. Our
prescription crib mattresses contain no flame retardant chemicals or other
toxins. Available with our patented 'Lever Support System' to give best
support to growing young bodies.
